Can't open PID file

hello,

this Can't open PID file issue keep on appearing for multiple services and when i check the file exists with a valid PID inside. this issue goes away after service restart.
why this issue keep on appearing again and again for multiple services in cwp pro?
see the below example for cwp-phpfpm service .

[root@server ~]# service cwp-phpfpm status -l
